The article didn't say how they calculate mileage?
Beginning in 2012, drivers of an average passenger car will pay euro0.03 per 1 kilometer (7 US cents per mile). But annual road taxes and purchase tax for new cars will be abolished, reducing the cost of a new car by 25 percent.
The government says nearly six out of 10 drivers will benefit under the system, which shifts the tax burden to people who drive the most and at peak hours. Congestion is expected to be halved and carbon emissions cut 10 percent.
